PROCESS OF AND MACHINE FOR EIVIBEDDING WIRE IN GLASS.

'l SPECIFICATION forming part of Letters Patent No. 605,754, dated June 14,1898.

I Application filed January 20, 1896. Serial No. 576,186. (No model.)

chinery for carrying out such process, the invention being especially applicable to the production of thin sheets containing light wire and the process and apparatus being such that a product of that character can be made with rapidity and Without any material disturbance ofthe molten glass or distortion of the heated wire. y

In the accompanying drawings, Figure 1 is a longitudinal section of a machine embodying my improvements. Fig. 2 is a plan View,

and Fig. 3 is an enlarged view of a portion of Y Fig. l. A Y

A is a plate-glass-rolling table which may be of any-ordinary construction, said table having in this instance rails a a., upon which run the rollers B O, extending across the table' and having end tIanges to prevent lateral displacement.A The said rolls are mounted so as to be free to turn in bearings on a Vcarriage D, which may be operated by means of an electric motor mounted on the carriage, as represented by dotted lines in Fig. l, said motor being geared to the rear roll O.' It will be understood, however, that carriage and rolls may be driven in any desired manner, the manner of driving the same being no part of my present invention.

The weight of the carriage may be varied and regulated at will by the use of suitable weights, as indicated by dotted lines in Fig. l of the drawings.

The front roll B is provided with ribs d, The plain rear roll is adjusted in respect to the ribbed front roll, so that its surface will be slightly nearer the bed than the base of the groove between the ribs of the ribbed'roll, 'so that the plain roll will roll down the ribs formed in the glass and thus close the openings formed. bythe ribs of the ribbed roll.

Carried by'a bracket e, projecting in front of the carriage D, is a chute E for the wire or wire-gauze which it is desired to embed in the glass, and this chute is pivoted in the present instance to the bracket at c, so that it may be swung to the position shown by dotted lines while the molten glass is being poured upon the table, and that being done may be swung into operative position, as shown by full lines.

Adapted to slide on the table in front of the ribbed roll Bis a plow F, havingits sidesff tied together by rods or bars f' f2, the latter of which, in the operation of the machine, acts as a continuation of the chute E, so as to extend the guide-for thetwire onwire-gauze to a point as near the ribbed roller as possible, and thereby. more effectually support and keep straight, While descending, the sheet of wire, which whenprojected into contact with the molten glass'becomes highly heated and very flexible.

The sheet of wire-gauze having been placed upon the chute E, a proper quantity of molten `glass is poured on the table directly in front of the ribbed roll B, and between the walls of the plow F and the lower end of the wire-gauze.

sheet is allowed to drop upon the molten glass immediately in front of roll B,so that the latter Vpart of a plate being rolled should be what is termed chilled glass the wire is not embedded in said chilled portion,which is usually out from the plate after annealing.

The ribbed-roll B serves not only to positively'force the Wire into thev glass until it reaches the position in which'it is to remain therein, but at the same time and place it rolls the glass into a sheetof uniform thickness, having in its upper face grooves or depressions formed by the ribs d and by the wire forced into the glass, the smooth roll O effecting the final complete covering of the wire and the production of smooth faces on both sides of the sheet of glass by rolling down that surface of said glass sheet through which the wire'has been forced.y By this means I am enabled to produce with great rapidity thin sheets containing lightl wire without any material disturbance of the molten glass or distortion of the heated wire.

Having thus described my invention, I

IOO

claim and desire to secure by Letters Patentl. The process herein described of producinlbr what is known as Wire-glass, said proeess consistingY in simultaneously and coincidently forcing the Wire into the glass until it reaches the position in which it is to remain therein and rolling the glass into a sheet, and then covering the embedded wire by rolling down that surface of the glass through which the Wire Was forced.

2. In a Wire-glass-making machine, the combination of a table, a roller mounted to travel at suoli a fixed distance above the same that the Wire to be forced into the glass will be forced to the place Where it is to remain therein, said roller having spaced ribs on its periphery, and means for feeding a sheet of wire down in front of the roller and to be forced thereby into a mass of glass placed on the table in front of the same, whereby the Wire will be pressed into the glass until it reaches the position in which it is to remain therein, and the glass will, at the same time and place, be rolled into a sheet of uniform thickness, substantially as described.

il. In a wire-glass-makingmachine, the conibination of a table, a roller mounted to travel at such a fixed distance above the same that the wire to be forced into the glass will be forced to the place where it is to remain therein, said roller having spaced ribs on its periphery, means for feeding a sheet of Wire down in front of the roller, and to be forced thereby into a mass of glass placed. on the table in front of the same, and a roll following` the ribbed roll, and having its surface closer to the table than the bases of the ribs on said ribbed roll, whereby the wire is pressed into the glass until it reaches the position in which it is to remain therein, the glass is at the same time and place rolled into a sheet of uniform thickness, and the projecting ribs in the upper surface of the glass are finally rolled down, so as to cover and inclose the embedded wire, substfniiially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
